D'Addario Planet Waves Screetching Halt Humidifier

About This Item

The D'Addario Screeching Halt Humidifier allows you to humidify your guitar's body and neck joint, even in the driest conditions—while on display, or during extended periods when your instrument will be outside its case.

The humidifier releases moisture slowly and evenly while capturing the vapor inside the body of the instrument to retain the proper humidity level. Maintaining the humidifier is as simple as moistening the sponge when the humidity falls below a safe level (40-60% Relative Humidity). The Screeching Halt Humidifier can also be used as a feedback reducer when playing live, keeping your guitar properly humidified even during performances.

D'Addario is known for innovative, problem-solving, quality musical accessories, offering a complete line of award-winning accessories including cables, picks, tuners, capos, straps, humidifiers, maintenance tools and more.

Screetching Halt Humidifier


Verified Buyer

This is a great way to provide humidity to a guitar that someone prefers to keep out of the case. It fits perfectly in a standard sound hole of an acoustic guitar as noted in the product description, and it is east to use. The sponge is as described able to hold a nice amount of water so you don't have to check all the time as to how damp it is.


Didn't fit my guitar.


Verified Buyer

I have a Martin OMCPA-4 electric acoustic guitar. I bought this humidifier specifically for that instrument, and when I went to test fit it in the C-hole; instead of fitting in, it sat over the ring inlays. Very disappointed as I like the whole idea of that humidifier's design. I plan on returning the item.

Response from StewMac
